[Solved]-Highcharts -- show axis labels on extreme edges-Highcharts

Believe it or not, Highcharts has the following property yAxis.showLastLabel and it's default value is false (even though the documentation says the default is true).

This has screwed me over more than once. Set it to true and you're good to go.

{
  yAxis: {
    showLastLabel: true
  }
}
